This invention relates to a washing-machine which includes a fixed cylindrical outer drum, whose axis is horizontal, and a'rotary perforated inner drum coaxial with the outer drum, the inner drum being subdivided into compartments, each adapted to receive and tumble fabrics, and to receive water confined in the outer drum.

One object of the invention is to provide an improved relative arrangement of the compartments of the inner drum, and of openings in the two drums, whereby, when the inner drum is at rest, fabrics which have been washed in one compartment may be discharged by gravity through'coinciding openings in the drums, and at the same time, another compartment may receive unwashed fabrics dropped into it through other coinciding openings. v

Other objects will hereinafter appear.

Of the accompanying drawings forming a part of this specification,

Figurel is a side elevation of a washingmachine embodying the invention, looking toward the front side.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a fragmentary pers' ective sectional view, showing portions 0 the inner drum.

Figure 4 is an enlargement of a portion of Figure 2.

Figure 5 is an end view of the machine, showing means for receiving washed fabrics from one compartment of the inner drum, and means for delivering unwashed fabrics to another compartment.

The same reference characters indicate the sameparts in all of the figures.

In the drawings, 12 designates the cylindrical outer drum, which may be of any suitable construction, and fixedly supported by feet 13, with its axis horizontal, it lower portion being adapted, to confine water which acts on the fabrics in the inner drum. The normal water line may be at 14 (-Fig. 2). The outer drum has an upper receiving 0 ening 15, located in the top portion and a ove the axis, and a lower delivering openin 16, in the front side, the lower edge of the ront opening being lower than the axis of the drum and higher than the normal water line. The receiving opening 15 is provided with a closure 17, and the delivering openin with a closure 18., Said closures are pre erably curved slides movable in guides on the external surface of the drum, and connected b curved straps 20, so that they are simul taneously movable to open and close the openlugs.

21 designates the hollow cylindrical body of the inner drum, composed of sheet metal suitably perforated, to permit the entrance to its interior of water contained in the outer drum, the ends of the body being closed by heads 22, indicated by dotted lines in Figure 1. The inner drum is coaxial with the outer drum, its axis being provided by alined stub shafts or trunnions 23 and 24, journaled in bearings 25 on the opposite ends of the outer drum. The inner drum is rotated in the direction of the arrow X (Figure 2), by the usual or any suitable mechanism provided for that purpose. While portions of said mechanism are shownby Figure 1, I do not describe the same, because my invention does not re. late thereto.

. The inner drum is provided with sheet metal partitions 26, radiating from its axial center to the body 21, and subdividing the interior of the drum into a plurality of compartments, each of which is a segment of a hollow cylinder. The partitions are preferably reinforced by angle bars 27 at their meeting edge portions, as shown by Figure 3. The inner drum is provided with o ening's 28, for the insertion and removal of abrics, the opposite longitudinal edges 28 and 28 of one of said openings being indicated by Figure 4. The edge 28 of each opening 28, is substan- 'tially flush with a parti ion 26, so that washed fabrics may slide by gravit' on a partition aptd through an opening, as escribed hereina er.

The inner drum is provided with closures 29, for said openings, said closures being preferably curved slides movable in curved guides on the outer surface of the inner drum. One opening 28, and its closure 29, are shown by Figure 4, a guide for said closure being shown at 30, and a stop at 32.

. The arrangement shown by the drawin s is such that when the inner drum is arrestefi, with the outer end of one of its radial partitions 26 at approximately the level of the lower edge of the delivering opening 16 of' the outer drum, as shown by Figure 2, an innerdrum opening 28 registers with the delivering opening 16, and said partition is inclined, so that washed fabrics 33 may slide from the partition and be discharged by gravity through the registering openings into a truck, or other receptacle 34, (Figure 5). At the same time, the opening 28 of another compartment registers with the receiving opening 15 of the outer drum, so that unwashed fabrics may be dropped by a conveyor 35 (Figure 5) into the last-mentioned coinpartment.

As indicated by Figures 2 and 3, the inner drum 21 and the partitions 26 are provided with alternating perforated and imperforate portions. The inner end portions of the partitions are provided with perforations 36, and their outer end portions are imperforate, as best shown by Figure 3. The imperforate outer portions of the partitions abut imperforate portions of the inner drum, formed in this instance by the closures 29, the inner drum being provided with perforations 37, spaced from the partitions 26. The imperforate outer portions of the partitions and the imperforate closures collectively form angular water receptacles. Each receptacle receives a charge 38 of water from the outer 4 drum, when the compartment is at the lower part of its circular path, as shown by Figure 2, and spills the charge upon fabrics being washed, when the compartment reaches a higher point in its path, the washing opera tion being thus facilitated. Y

The inner drum and its partitions are provided with rub ribs projecting into the compartments, said ribs being preferably holow and of perforated sheet metal. The rub ribs on the drum are designated by 39, and are located between the outer ends of the partitions 26. The ribs on the partitions are designated by 40, and are located between the inner and outer ends of the partitions, in position to support fabrics in the path of the water charges 38, spilled from the receptacles above describe The inner drum may be provided with a transverse partition 41 (Figure 3) subdividing the compartments of said drum into two parts. In other words, the inner drum has two groups of compartments arranged in tandem order, the outer drum being provided with two receiving openings, two delivering openings, two closures 17, and two closures 18. all as indicated by-Figure 1.

I claim:

1.- A washing-machine comprising a fixed cylindrical outer drum, having a horizontal axis, an upper receiving opening above the axis, a lower delivering opening whose lower edge is lower than the axis, and closures for said openings; and a rotary cylindrical inner drum coaxial with the outer drum, and havin artitions radiating from its axial center and subdividing its interior into a plurality of com artments, each of which is a segment of a ho low cylinder, said inner drum having openings and closures therefor, said openings communicating with the compartments and being movable into registration with the receiving and delivering openings, one edge of each inner drum opening being substantially flush with a radial partition, the arrangement being such that when the outer end of a radial partition is at the level of the lower edge of the delivering opening, an inner drum opening registers with the delivering opening, and said partition is inclined so that washed fabrics may slide therefrom and be discharged by gravity through saidregistering openings.

2. A washing-machine as specified by claim 1, the receiving opening being spaced from the delivering opening, and the inner-drum openings from each other, to permit registration of one inner-drum opening with the receiving opening, while another inner-drum opening registers with the delivering opening, so that unwashed fabrics may be dropped into one compartment through the receiving opening, while washedfabrics are being discharged by gravity from another compartment, through the delivering opening.

3. -A washing-machine comprising a fixed outer drum having a horizontal axis, anv upper receiving opening above theaxis, a lower delivering opening whose lower edge is lower than the axis, closures for said openings, and a rotary inner drum coaxial with the outer drum, and having radial partitions subdividing its interior into compartments, each of which is 'a segment of a hollow cylinder, said inner drum having openings and closures therefor, said openings communicating with the compartments and being movable into registration with the receiving and delivering openings, the inner drum and partitions being each provided with alternating perforated and 'lmperforate portions, relatively arranged to form angular water receptacles at the intersection of the partitions with the drum, the arrangement being such that the water receptacles of each compartment is charged with water from the outer drum, when the compartment is at the lower part of its circular path and spills its charge upon fabrics being washed, when the com artment reaches a higher point, the inner rum and partitions being each provided with rub ribs 11 ARTHUR BRANNEN.
